MOTOR-DRIVEN MIXER AND THE LIKE.

Application led July 7,

To all whom t may concern:

Be it'known that I, BOY WV. Poo-R, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Motor-Driven Mixers and the like, of which the following is a specification. A

This invention relates to motor driven mixers and the like, and more particularly to mixers for domestic and culinary purposes, such as for stirring, mixing and commingling salad dressings, pastes and the like, and for beating or whipping eggs, cream and other culinary mixtures, or agitating the same or any other substance. The invention has for its object to provide an improved device of this character which may be readily operated by power readily available in dwelling houses and apartments, more particularly the power to be derived from water flowing from a tap or faucet, and which device may be readily put into position of use or service or removed therefrom, and which will be generally superior in simplicity and inexpensiveness, taken in conjunction with durability, convenience, positiveness and speed in use, convenience'in assembling or disconnecting of parts for charging or emptying or for cleaning or repair, compactness in form, and general etliciency, economy in use, and serviceability.

With the above and otherobjects in View, the invention consists in the novel and useful provision, formation, combination, association, relative arrangement, mode of 0peration and application of pfgts, members and features, all as hereinafter described, shown in the drawing, and finally pointed outl in claims.

In the drawing:

Figure l is a side elevation of a motor driven mixer, stirrer, or agitator, embody' ing the invention, and applied in position for service; and,

Figure 2 is an enlarged detail fragmentary central vertical sectional View of the same, parts being in elevation.

Corresponding parts in both figures are designated by the same reference characters.

Referring with particularity to the drawing, there is shown therein my improved motor driven mixer, particularly useful for domestic purposes (although it will be un- 1921. serial No. 422,994.

derstood that the invention in suitably and readily suggested forms may be used for industrial purposes or in restaurants or hotels or otherwise), such mixer or beater or stirrer comprising a jar or receptacle A, indicated in the drawing as a Mason jar or the like, having the usual exteriorly threaded neck or orifice portion a, to which orifice portion is applied a cap or head member` B in conjunction with which is mounted a motor element C, such motor element being applied to or coupled with a mixer, stirrer or agitator shaftc at the lower end of which is mounted a mixer, stirrer or agitator D shown as comprising a plurality of looped wires 3 secured at the looped ends to a disc or head 4 suitably attached tothe shaft c, as by a sctscrew 5, and adapted to be received in operative position within the jar or con-l tainer A. Such head or cap B is provided with a threaded flange 5 adapted to be applied to the threads a of thev jar A, to close or seal up such j ar or receptacle and its contents, the cap or head B having a base member or plate 6 extending across the mouth of the receptacle when the cap or head is in place. The head or ea B is provided with means E through whic i communication may be had with the interior of the jar or receptacle A so that ingredients or materials may be introduced to such jar or receptacle during the stirring, mixing or agitating operation, in sequence, or as desired, and through which, as may be found convenient or desirable, fluid contents or semi-fluid contents of the container may be decanted without removing the cap or head B. .Such means E may comprise a spout 7 provided at one side of an upstanding annular wall 8 of the head, which wall, with the base plate 6 and a top wall 9, comprise the cap or head. The spout 7 communicates, by" an opening 10, in such annular wall 8, with a tubular conduit 11 angled at the top within the ca B and dependino' below the base wall 6 t ereof within the Jar orreceptacle A. Mounted upon the shaft c, detachably, is the motor element C, the same in the form shown in the drawing comprising adisc or wheel 12 provided upon by a stream of water entering into such casing or head B at one side, as through a y tainern iexible tube 14, the partially spent or discharged water passing out of said head or casing through a discharge opening 15, the inlet pipe 14 and discharge opening 15 being arranged in al chord of the circle described by the annular wall 8, at one side of the center of said casing or head. The shaft c operates in a sleeve bearing 16 depending from the base plate 6, a cupI 17 `being detachably applied to such shaft, as by threads 18, beneath said sleeve bearing, and a thrust bearing 19 being loosely applied to the shaft c above the bottom member 6, an inverted cup 21 being detachably applied to the shaft o between the thrust bearing 19 and the disc 12, the disc 12 and cup 21 being held fast to the shaft c by a key 20, and the entire assemblage of the shaft group of elements recited being conserved, by a nut 23 applied to threads 22 at the upper end of the shaft c.

1n Figure 1 the device is shown as connected, for service, with a faucet 1*", such as a sink or lavatory faucet for delivering water for domestic purposes, and having the usual handle member 24 and spout 25, over which spout the flexible tubing 14 is passed, at one end thereof, which end portion is provided with a slip-joint coupling 26.

When the water is turned on at the faucet l?, the stream thereof will be projected against the buckets 13 and cause rotation thereof and of the shaft c, the waste water passing out through the discharge opening 15 into the sink or lavatory or tub or otherwise disposed of. The buckets 13 and disc 12 as they rotate will turn the shaft c and in turn operate the beater or stirrer or mixer or agitator wires 3, so that ingredients or materials in the container A will be suitably acted upon, whether they be the ingredients of a salad dressing, an egg or egg mixture, or whatever the fluid or semi-fluid contents may be. Further ingredients may be added from time to time by pouring .the same through the spout 7 and down through the conduit or tube 11 and into the con- Thus, inmaking salad dressing, oil, vinegar and other ingredientsmay be successively introduced at the proper stages `of the mixing. beating, whipping' or agitating action. The cups 17 and 21 will serve effectively to prevent escape of the contents by leakage upwardly of the shaft c. 'llhe head or cap B will readily be detached 'from the receptacle A, by the threads a and 5 so that. the receptacle A may be filled, or its contents decanted or discharged, and so that the beater or agitator D and the interior of the receptacle A may be cleaned.

By employing a number of receptacles A., the same may be utilized for the agitating or stirring of their contents, successively, being successively prepared to that end,

iaeeaae while the next preceding receptacle in each instance is in use in conjunction with the head B and attendant features. lin this way exceedingly speedy operation for the stirring, mixing, beating or agitating of many successive batches or charges of material may be carried on conveniently and etfectively.

The device is extremely simple in construction and not likely to get out of repair or order, and its use may be carried on coning a receptacle, and a detachable cover unit therefor, said cover unit comprising a chamber, a motor element mounted within the chamber, a beater element adapted to be arranged within the receptacle and operated by said motor element, and means extending through a. part of said chamber and establishing communication between the interior of' the receptacle and the outside.

2. A device of the class described including a receptacle, and a detachable cover unit therefor, said cover unit comprising a chamn ber, a motor element mounted wit-hin the chamber, a beater element adapted to be arranged within the receptacle and operated by said motor element, and a conduit extending through a portion of said chamber and establishing communication between 'the outside of the cover and the interior of the receptacle.

8. A device of the class described including a receptacle, and a detachable cover unit therefor, said cover unit comprising a chamber, a motor element mounted within the chamber, a beater element adapted to be arranged within the receptacle and operated by said motor element, a conduit comprising a funnel on the exterior of the cover unit and an interior tubular portion in communication therewith, said tubular portion passing thro-ugh a portion of said chamber of the cover unit.

1n testimony whereof, lf have signed my name to this specification in the presence of two subscribing witnesses.
